Receiving channel arrangement for tracing code multiplex signal for satellite navigation of vehicle, has source selection register selecting pseudo coincidence spreading code, and submodulation masks selecting source selection register

摘要

The arrangement (100) has submodulation mask registers (112, 114) containing submodulation masks, and code memories (108, 110) containing a pseudo coincidence spreading code. A source selection register (116) selects the pseudo coincidence spreading code, and the submodulation masks select the source selection register. A modulation mask selection register (134) contains a value for selection of the submodulation masks. The source selection register contains a value, which determines whether the source selection register or the modulation mask selection register selects the masks.
